In mechanical production, a mold is often used to produce a corresponding workpiece. The die often needs to cut the blank to a suitable size to make the corresponding workpiece, and during the cutting process, the blank inevitably generates much dust. The dust may cause pits and convex hulls on the workpiece, resulting in the workpiece being unusable, and therefore a dust suction device is generally required to suck the dust. In current dust suction device, suction generating device often all is direct suction dust, and this often can lead to the dust can't in time clear up, the accumulation appears, influences follow-up use.
In view of the above, the present invention provides a suction force generating device, and fig. 1 is a view showing an embodiment of the suction force generating device according to the present invention, and please refer to fig. 1.
Referring to fig. 1, the present invention provides a suction force generating device 100, including an air inlet pipe 1 and an air transmission pipe 2 which are communicated with each other, where the air transmission pipe 2 includes an air transmission section 21 and an absorption section 22 which are communicated with each other, an air outlet 211 is disposed at an end of the air transmission section 21 away from the absorption section 22, an absorption port 221 is disposed at an end of the absorption section 22 away from the air transmission section 21 to face a workpiece, a diameter of the air transmission section 21 is greater than a diameter of the absorption section 22, and a connection portion between the air inlet pipe 1 and the air transmission section 21 and the absorption section 22 is communicated.
In the technical solution of the present invention, when the air intake duct 1 of the suction generator 100 is used for air intake, an air flow enters the air transmission duct 2 from the air intake duct 1. The diameter of the gas transmission section 21 is larger than that of the suction section 22, so that the gas flow is input from the gas inlet pipe 1 into the gas transmission section 21. When the high-speed air flow passes through the air conveying section 21, a certain negative pressure is generated in the suction section 22, which causes the suction port 221 to generate a certain suction force, thereby sucking the dust near the workpiece. The dust flows together with the air flow in the suction force generating device 100 until discharged from the air outlet 211 to the outside. So make suction generating device 100 can produce the suction, absorb the dust to directly arrange the dust to the external world, make the clearance cycle extension, very facilitate the use.
Further, the diameter of the gas transmission section 21 is D, the diameter of the suction section 22 is D, wherein D/D is more than or equal to 1.2 and less than or equal to 1.5. In this embodiment, the diameter of the gas transmission section 21 is larger than that of the suction section 22, so that most of the gas flow can flow towards the gas transmission section 21, but when the gas transmission section 21 is too large, the flow rate of the gas flow is reduced, so that the suction force is reduced, and when the diameter of the suction section 22 is too small, the range of dust suction is small, and the use effect is poor. Therefore, the difference between the diameter of the gas transmission section 21 and the diameter of the suction section 22 needs to be in a proper range, generally, the ratio of the diameter of the gas transmission section 21 to the diameter of the suction section 22 needs to be greater than or equal to 1.2 and less than or equal to 1.5, and generally 1.3 is the best effect, at this time, the suction force of the suction force generating device 100 is sufficient, and the suction range of the suction port 221 is also large.
Further, the suction generating device 100 further includes: a main body part 3, an air delivery part 4 and a suction part 5. The gas transmission pipeline 2 and the gas inlet pipeline 1 are arranged in the main body part 3; the gas transmission part 4 is detachably connected with the main body part 3, and the gas transmission section 21 is arranged in the gas transmission part 4, so that when the gas transmission part 4 is connected with the main body part 3, the gas transmission section 21 is communicated with one end of the gas transmission pipeline 2 in the main body part 3; the suction part 5 is detachably connected with the main body part 3, and the suction section 22 is arranged inside the suction part 5, so that when the suction part 5 is connected with the main body part 3, the suction section 22 is communicated with the other end of the gas transmission pipeline 2 in the main body part 3.
In this embodiment, a part of the gas transmission pipeline 2 is disposed in the main body portion 3, and the diameter of the gas transmission pipeline 2 in the main body portion 3 is generally larger than the suction section 22 and smaller than the gas transmission section 21, so as to prevent the disturbance of the flow of the gas flow. The gas transmission part 4 and the suction part 5 are detachably connected with the main body part 3 respectively, so that the main body part 3 can replace the gas transmission part 4 and the suction part 5 with different specifications, and the suction force generation device 100 can meet different use requirements.
Specifically, the main body portion 3 is provided with two mounting grooves 31 in the gas transmission pipeline 2, and the suction port 221 and the exhaust port 211 are respectively located at the bottoms of the two mounting grooves 31; the gas transmission part 4 and the suction part 5 are respectively provided with a matching part 41 which is used for extending into the mounting groove 31 and corresponds to the mounting groove 31, and the outer part of the matching part 41 and the inner side wall of the mounting groove 31 are correspondingly provided with taper threads so as to respectively connect the main body part 3 with the suction part 5 and the gas transmission part 4.
In this embodiment, the two mounting grooves 31 and the two matching portions 41 are arranged in a one-to-one correspondence manner, and when the gas transmission portion 4 and the suction portion 5 are mounted, the matching portions 41 only need to be inserted into the corresponding mounting grooves 31 to be in threaded connection. The mounting groove 31 and the matching part 41 are provided with tapered threads, and the tapered threads can prevent gas leakage. In a specific application, the matching portion 41 is generally a bump, and a sealant may be coated between the matching portion 41 and the mounting groove 31, so that the sealing capability is more excellent.
Further, the gas transmission pipeline 2 in the main body part 3 is arranged in a tapered manner in the direction from the gas transmission section 21 to the suction section 22. In this embodiment, the gas transmission pipeline 2 in the main body 3 is disposed in a tapered manner in a direction from the gas transmission section 21 to the suction section 22, so that the airflow entering the main body 3 from the gas inlet pipeline 1 can enter the gas transmission section 21 more smoothly, and the suction force generated by the suction force generating device 100 is more stable.
Further, the air inlet pipe 1 is obliquely arranged towards the air transmission section 21, so that the air flow in the air inlet pipe 1 can enter the air transmission section 21 more smoothly, and the suction force generated by the suction force generating device 100 is more stable.
Specifically, when the deflection angle of the air inlet duct 1 is too large, the suction force generating device 100 may not be able to generate the suction force normally, and generally, the deflection angle of the air inlet duct 1 is 3 degrees to 10 degrees, so that the suction force is not affected too much, and the air flow can enter the air conveying section 21 smoothly.
Specifically, when the deflection angle of the air intake duct 1 is 5 degrees, the air flow guiding effect is better, and the influence of the suction force is smaller, which is generally suitable. Of course, in a specific production, it is difficult to deflect the air intake duct 1 by 5 degrees in millicentimetres, as long as the deflection angle of the air intake duct 1 is within 3 to 10 degrees.
Further, the suction generating device 100 further includes at least one hose, one end of the hose is communicated with the suction port 221, and the other end of the hose is disposed near the dust. In this embodiment, the suction port 221 may be difficult to approach the workpiece in a specific use, so that dust cannot be sucked. The suction generating device 100 can therefore generally also be provided with a hose, through which dust is sucked off. It is noted that the hose may be provided in plural numbers so that dust can be adsorbed from different places at the same time, but the number of the hose is not so large because it disperses the suction force, which may cause the suction force to be insufficient, and generally, it is appropriate that the number of the hose is not more than 3.
Referring to fig. 2, the present invention further provides a dust suction device 1000 for sucking dust generated when a die cuts a workpiece, wherein the dust suction device 1000 includes: a suction generating device 100, a gas transmission device 200, a sensing device and a control device 300.

In this embodiment, the dust sucking and removing device 1000 sends the air flow to the suction generating device 100 through the air conveying device 200, and the control device 300 can control the on/off of the air conveying device 200, so as to control the generation and disappearance of the suction force in the suction generating device 100. The control device 300 determines whether suction needs to be generated by sensing the position of a cutter of the die through the sensing device, the sensing device sends out the suction signal when sensing that the cutter reaches the first preset position where the workpiece is to be cut, and at the moment, the control device 300 controls the gas transmission device 200 to transmit gas to generate suction to prepare for suction of dust generated when the cutter cuts the workpiece; the sensing device sends the stop signal when sensing that the tool reaches the second preset position far away from the workpiece, at this time, the suction generating device 100 generally has already sucked the dust, so the control device 300 may also control the gas transmission device 200 to stop gas transmission when receiving the stop signal, thereby reducing the energy consumption of the dust sucking device 1000.
Referring to fig. 3, the control device 300 is electrically connected to the sensing device and the gas transmission device 200, respectively, for controlling the dust absorption device 1000 to absorb dust.
The control device 300 may include: a processor 1001, such as a CPU, a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Wherein a communication bus 1002 is used to enable connective communication between these components. The user interface 1003 may include a Display screen (Display), an input unit such as a Keyboard (Keyboard), and the optional user interface 1003 may also include a standard wired interface, a wireless interface. The network interface 1004 may optionally include a standard wired interface, a wireless interface (e.g., WI-FI interface). The memory 1005 may be a high-speed RAM memory or a non-volatile memory (e.g., a magnetic disk memory). The memory 1005 may alternatively be a storage device separate from the processor 1001.
As shown in fig. 3, the memory 1005, which is a kind of computer storage medium, may include therein an operating system, a network communication module, a user interface module, and a control program of the dust suction device 1000.
In the control device 300 shown in fig. 3, the control program of the dust suction device 1000 stored in the memory 1005 is called by the processor 1001, and the following operations are performed:
